Dylan O'Brien Reveals He Suffered From Panic Attacks While Recuperating from 'Maze Runner' Injuries

Dylan O’Brien is finally opening up about the injuries he sustained on The Maze Runner: The Death Cure set and all that he went through to get better as he signed on for another movie — American Assassin.

The actor revealed that he actually had to have facial reconstructive surgery, after suffering from a “severe concussion and brain trauma.”

“I basically broke this whole side of my face,” Dylan shared, indicating the right side of his face.

Speaking later with Vulture, Dylan revealed his road to recovery was slow, but still promising on top of the panic attacks he was having.

For American Assassin, he had to learn fight choreography and spent in the gym with action coordinator Roger Yuan, although he was still struggling with heavy emotional and psychological episodes during his recovery.

“Sometimes I’d literally show up at the gym having a panic attack, and my trainer would be like, ‘All right, let’s just go get breakfast,’” he shared. “I can’t give enough credit to him [Yuan]…he was really there for me, and not just like a trainer where it’s like, ‘Well, come on, man, I gotta pump you up.’ He cared more about my mind and the state that I was in.”

Even before leaving to start filming, Dylan was still overcoming his anxiety.

Thankfully, girlfriend Britt Robertson and his dad Patrick were there by his side, and Patrick actually went to London to film with him.

“I didn’t even think they’d let me on the plane, to be honest,” Dylan says. “I must have looked high or something…I don’t think I would have been able to step onto the plane without him.”

American Assassin opens next Friday.
